Celtic boss Ange Postecoglou admits striker Giorgos Giakoumakis is a "50-50" shot to make it for Wednesday's crunch clash with St Mirren.
The Greek striker netted a hat-trick against Dundee but was absent for the clash with Hibs due to an illness.
And his eye for goal was badly missed as his side stumbled to a toothless 0-0 stalemate in his absence.
But Postecoglou admits there's no guarantees he will feature against the Buddies, despite giving a hopeful update before the game at Easter Road.
The hope is the Greek striker will feature, however, he may have to make do with a place on the bench.
"Giako is still 50-50," Postecoglou said. "He is better. I will probably make a decision on him tomorrow (Wednesday) morning.
"If I had to make a call he probably won't start but he might be involved. But I will wait and see how he's feeling."
And the Celtic boss admits he's chuffed about the thought of returning Down Under for the first time in three years.
The Parkhead side will join Rangers and two their teams for a glamour tournament just before the World Cup kicks off.
He added: "It'll be emotional. A lot of guys I grew up with are die hard Celtic fans and they get to see their mate bringing Celtic down under. It'll be special for sure."
